Understanding the influence of outcome valence in bargaining: A study on fairness accessibility, norms, and behavior

In this study we investigate how outcome valence affects the importance of self-interest and fairness in ultimatum bargaining. In three experiments we systematically study the effect of outcome valence on fairness accessibility, norms, and behavior. Results on all three aspects show strong evidence for the hypothesis that fairness becomes more important and self-interest becomes less important in negative valence bargaining. Fairness accessibility was higher when bargaining involved negative payoffs than when it involved positive payoffs (Experiment 1), the fairness norm was stronger in negatively versus positively valenced bargaining when an identical unequal offer benefiting the allocators was evaluated (Experiment 2), and allocators allocated more to recipients in negative valence bargaining than in positive valence bargaining (Experiment 3). We relate our findings to insights derived from the do-no-harm principle.     

Neural correlates of written emotion word processing: a review of recent electrophysiological and hemodynamic neuroimaging studies

A growing body of literature investigating the neural correlates of emotion word processing has emerged in recent years. Written words have been shown to represent a suitable means to study emotion processing and most importantly to address the distinct and interactive contributions of the two dimensions of emotion: valence and arousal. The aim of the present review is to integrate findings from electrophysiological (ERP) and hemodynamic neuroimaging (fMRI) studies in order to provide a better understanding of emotion word processing. It provides an up-to-date review of recent ERP studies since the review by Kissler et al. (2006) as well as the first review of hemodynamic brain imaging studies in the field. A discussion of theoretical and methodological issues is also presented, along with suggestions for future research.     

“右好左坏”和“左好右坏”——利手与左右空间情感效价的关联性

人们会将“右”和“左”与积极或消极的事物相关联,这称为左右空间的情感效价.以具身认知理论和躯体特异性假设为基础的研究发现,右利手会将右侧空间与积极事物相关联,而左利手则会将左侧空间与积极事物相关连;左右空间情感效价是由利手与非利手的运动经验塑造的;利手与非利手运动经验的改变则会反转左右空间情感效价;趋近动机脑功能偏侧化与利手是一致的.未来的研究应进一步澄清利手运动与趋近动机在神经机制上的关联性,并探索文化因素与身体经验如何共同塑造左右空间情感效价.

Abstract

Of all the research programs investigating radical life extension, cybernetic immortality is, by definition, the most ambitious. Several models fall within this category. While some include the possibility of “re-corporealizing” either as machine, biological entity, or hybrid, all models have several essentials in common. They require the ability to construct a non-biological (e.g., electronic) substrate that can model the functioning human brain, including the ability for consciousness (self-awareness) and a means for uploading into this artificial mind the contents of one's mortal life experiences. The individuals who have speculated most comprehensively on this include Ted Chu, Raymond Kurzweil, and Martine Rothblatt.¹1 Relevant books include: Ted Chu, Human Purpose and Transhuman Potential: A Cosmic Vision for Our Future Evolution (San Rafael, CA: Origin Press, 2014); Michio Kaku, The Future of the Mind: The Scientific Quest to Understand, Enhance, and Empower the Mind (New York: Doubleday, 2014); Ray Kurzweil, How to Create a Mind: The Secret of Human Thought Revealed (London: Penguin, 2013); Martine Rothblatt, Virtually Human: The Promise and the Peril of Digital Immortality (New York: St. Martin's Press, 2014).     

Contingency bias in probability judgement may arise from ambiguity regarding additional causes

We tested whether preventive and generative reasoning processes are symmetrical by keeping the training and testing of preventive (inhibitory) and generative (excitatory) causal cues as similar as possible. In Experiment 1, we extinguished excitors and inhibitors in a blocking design, in which each extinguished cause was presented in compound with a novel cause, with the same outcome occurring following the compound and following the novel cause alone. With this novel extinction procedure, the inhibitory cues seemed more likely to lose their properties than the excitatory cues. In Experiment 2, we investigated blocking of excitatory and inhibitory causes and found similar blocking effects. Taken together, these results suggest that acquisition of excitation and inhibition is similar, but that inhibition is more liable to extinguish with our extinction procedure. In addition, we used a variable outcome, and this enabled us to test the predictions of an inferential reasoning account about what happens when the outcome level is at its minimum or maximum (De Houwer, Beckers, & Glautier, 2002). We discuss the predictions of this inferential account, Rescorla and Wagner's (1972) model, and a connectionist model—the auto-associator.     

When old and frail is not the same: Dissociating category and stimulus effects in four implicit attitude measurement methods

It is not always clear whether implicit attitude measures assess the attitude towards single stimuli or the attitude towards categories. Nevertheless, this is important to know—both for interpreting implicit attitude effects and for selecting the test that is most appropriate for individual research aims. We investigated this for four implicit measures: the standard Implicit Association Test (IAT), the IAT-recoding free (IAT-RF), and two versions of the Extrinsic Affective Simon Task (EAST, identification (ID)-EAST). Effects in the standard IAT reflect evaluations of categories and single stimuli, whereas the IAT-RF measures attitudes towards categories only. Both versions of the EAST measure evaluations of single stimuli independently from the evaluation of categories. Three different effect sources are distinguished: attitudes towards single stimuli (IAT; EAST and ID-EAST), attitudes towards target categories (IAT and IAT-RF), and processes of recoding (IAT), which do not necessarily reflect attitudes.     

Gender differences in applying social cognitive career theory in engineering students

This study tested Social Cognitive Career Theory (SCCT) in predicting engineering interest and major choice goals among male and female college students. Participants were 579 sophomore engineering students who completed measures of self-efficacy beliefs, outcome expectations, interests, goals and social supports and barriers. Findings confirmed that the SCCT model produced a good fit to the data across gender. The findings also corroborated that women have less self-efficacy beliefs and interest than men. However, there are no statistically significant differences in measures relating to outcome expectations and goals. Moreover, women are more likely to perceive support, especially from peers and family, while men are more likely to perceive family barriers than women. For other supports and barriers there are no gender differences. Implications for future research and practice are discussed.     

Psychophysiological responses to cooperation: The role of outcome and gender

Instances of sustained cooperative behaviour in humans can be considered as an adaptive strategy that enhances the probability of reaching a goal. This study investigates psychophysiological responses to cooperation in healthy subjects, while considering outcome and gender as potential moderators of these responses. Salivary cortisol levels (Csal), heart rate (HR), skin conductance level (SCL), nonspecific skin conductance responses (NSRs), and mood states were measured at different points before, during and after a Lego house‐building task in undergraduate men (n = 22) and women (n = 20). Once the task was finished, the experimenter informed the participants about the outcome obtained (positive or negative). Cooperation produces an increase in HR, SCL, and NSR responses. When the outcome is positive it produces a gradual diminution in Csal levels, but when the outcome is negative there is a significant increase in Csal levels after the task followed by a progressive decrease. Men with positive outcomes showed a lower area under curve (AUC) in Csal than women with a negative outcome. Men had more NSR responses in all periods other than the rest period. Several mood states are differently affected by the combined effect of outcome and gender. Our laboratory results can be generalized to other situations in which negotiation, mediation, and cooperative strategies are relevant for taking decisions and/or solving problems.     

Sex Roles in Management: The Impact of Varying Power of Speech Style on Union Members' Perception of Satisfaction and Effectiveness

Effective management has traditionally been associated with men and masculine characteristics. In this study, I focused on manager communication, specifically the perceived effects of stereotypical gender/power speech styles. Union members viewed and rated a male and a female manager on videotape using three gender/power speech styles: stereotypical masculine (powerful), stereotypical feminine (powerless), and mixed gender/power. Union respondents judged both the male and female manager using the mixed gender/power speech style as most effective and as being associated with the most satisfied employees.     

Mood Induction in Children: Effect of the Affective Valence of a Text on Phonological Working Memory

The influence of mood on working memory capacity has been investigated in adults, albeit with conflicting results, but remains relatively unexplored in children. The present study examined the effect of a mood induction procedure on phonological working memory capacity in fourth and fifth graders. An initial working memory span test was followed first by a collective mood induction procedure, then by a second working memory span test. Results showed an effect of mood induction procedure on phonological working memory performances, with decreasing scores in the case of negative mood. These results suggest that, in certain contexts and situations, negative emotion has an impact on children’s cognitive abilities.
